    摘要: The gas-cooled electric machine of the present invention comprises a rotor, a stator having a core with radial ducts and slots on the inner surface, a winding arranged in the slots of the stator core, and slot wedges provided with projections arranged in the stator-to-rotor air gap lengthwise the longitudinal axis of the electric machine, the above said projections being provided on part of the slot wedges. Each of the projections has a base sloping towards the stator inner surface, a longitudinal rib adjacent the base end most removed from stator and facing the rotor, two side walls parallel to each other arranged in the stator transverse planes and facing the stator inner surface. The space formed between the projection base and the stator inner surface communicates with the radial ducts in the stator core. The present invention makes it possible to increase the output power of the electric machine within the existent overall dimensions thereof, or to reduce the consumption of materials and diminish the overall dimensions of the electric machine with a given output power thereof.
